The large bladder diverticulum in children.

Objective: Large bladder diverticulae, i.e. with a diameter measuring at least one-third of the bladder diameter on voiding cystourethrography, constitute an unusual but serious cause of obstructive uropathy in childhood.

Duplex collecting system diagnosed during the first 6 years of life after a first urinary tract infection: a study of 63 children.

Purpose: We determined the prevalence, anatomical variants and coexisting complications of duplex collecting systems in children with a history of UTI. Additionally, we compared the prevalence and severity of the coexisting anomalies with those found in single systems.

Materials And Methods: We reviewed the records of children younger than 6 years who were evaluated following a first UTI during a 9-year period to identify those with duplex systems.

Myogenic bladder decompensation in boys with a history of posterior urethral valves is caused by secondary bladder neck obstruction?

Objective: To investigate whether myogenic bladder decompensation in patients treated for congenital posterior urethral valves (PUV, the most serious cause of infravesical obstruction in male neonates and infants) may be secondary to bladder neck obstruction, as despite prompt ablation of PUV these patients can have dysfunctional voiding during later childhood or adolescence, the so-called 'valve bladder syndrome'.

Patients And Methods: The study comprised 18 boys (mean age 14 years, range 6.2-18.

Assessment of serum prostate specific antigen in childhood.

Objective: To investigate serum prostate specific antigen (PSA) levels with age and sex in childhood.

Subjects And Methods: This prospective study included 205 children (123 boys, 82 girls; mean age 59.27 months, sd 3.

Pelvi-ureteric junction obstruction by crossing renal vessels: clinical and imaging features.

Objective: To present the characteristic clinical and imaging findings of pelvi-ureteric junction (PUJ) obstruction caused by crossing renal vessels (CRV), as it presents particular features within the spectrum of congenital hydronephrosis.

Patients And Methods: Between April 1982 and December 2000, 384 children underwent surgery for PUJ obstruction. In 71 (18.

The long-term outcome of bilateral Cohen ureteric reimplantation under a common submucosal tunnel.

Objective: To analyse the results of bilateral Cohen reimplantation under a common submucosal tunnel, over an 18-year period.

Patients And Methods: We retrospectively examined 102 children (35 boys and 67 girls, median age 5.5 years, range 0.

Outcome of the distal ureteric stump after (hemi)nephrectomy and subtotal ureterectomy for reflux or obstruction.

Objective: To assess the outcome of the distal ureteric stump (DUS) after (hemi)nephrectomy with subtotal ureterectomy.

Patients And Methods: The records of 89 patients (median age 2.7 years, range 0.

Renal cell carcinoma in children under 14 years old: long-term survival.

Objectives: To assess the treatment and long-term survival of children under 14 years old operated upon for renal cell carcinoma (RCC).

Patients And Methods: The records of five patients (aged 2, 4, 6, 9 and 13 years) who had been treated for RCC between 1982 and 1993 were reviewed. All had undergone nephrectomy with (two) or without (three) regional lymphadenectomy.

Effects of submucosal Teflon paste injection in vesicoureteric reflux: results with 1- and 2-year follow-up data.

One hundred refluxing ureters with grades II (n = 65), III (n = 27) and IV (n = 8) vesicoureteric reflux (VUR) were treated with endoscopic submucosal polytetrafluoroethylene (Teflon) paste injection. Reflux stopped in 77 ureters after a single injection and in 13 ureters following a second injection. Two ureters remained with minimal (grade I) residual reflux, whilst in another 5 improvement from grades III and IV to grade II reflux was noted.

Urothelial tumors of the bladder.

Neoplasms originating from the transitional epithelium of the urinary bladder are rare in children. This paper examines the clinical, epidemiological and histopathological characteristics of 3 such cases. The patients were males aged 4, 8 and 14 years at the time of diagnosis.

Paediatric urolithiasis in Greece.

A group of 44 patients, aged from 10 months to 14 years, underwent surgery for urinary calculi over a 7-year period (1982-1989). Eleven patients had bilateral or multiple calculi (total number of stones = 55, 20 of which were staghorn). Metabolic disorders (n = 25) and Proteus urinary infection (n = 15) were the 2 factors most often associated with lithiasis.

Ostioplasty: a simple technique for ureterovesical reconstruction following intravesical ureterocelectomy.

A simple operation for the management of simple, i.e. intravesical, ureteroceles, which we have named 'ostioplasty', is presented.

Evaluation of open surgery for staghorn calculi in children.

We evaluated the results of open surgery in 19 children with staghorn calculi. The median age was 3.5 years (range 10 months to 14 years).

Surgical treatment of ectopic ureteroceles and the role of heminephrectomy with subtotal ureterectomy.

We evaluated 16 patients, 2 weeks to 8 years of age (median: 18 months), operated on for ectopic ureterocele. Five patients, in whom the upper kidney, drained by the ureter with the ureterocele, was viable, were submitted to excision of the ureterocele with reimplantation of the double ureter (n = 4) or high ureteroureterostomy (n = 1). A 2-week-old baby with a non-functioning kidney was treated by nephroureterectomy.

Microvascular changes in the early stage of reflux pyelonephritis. An experimental study in the pig kidney.

Renal microvascular changes were studied in the pig kidney during the initial stage of reflux pyelonephritis. In 10 piglets vesicoureteric reflux was surgically induced. The animals were then infected with a strain of Escherichia coli and sacrificed 2 weeks following the initiation of infection.

Coincident vesical transitional cell carcinoma and prostatic carcinoma. Clinical features and treatment.

Twenty-two patients with vesical urothelial carcinoma associated with prostatic carcinoma were reviewed. They represented 1.5% of the bladder and prostatic tumours treated in our department within a 12-year period from 1968 to 1979.

Multilocular cyst of the kidney.

The case of a 17-month-old girl with a multilocular renal cyst is presented. Clinically and radiologically the cyst simulated a Wilm's tumor and was treated by nephrectomy. Simple excision may be equally effective in a few cases provided a correct preoperative diagnosis of the nature and extent of the lesion can be made.
